Reconstitute lyophilized antibody using ultrapure to a final concentration no less than 100 ug/mL. Reconstitution with PBS or Tris buffer is acceptable if required. Protein carrier, biocide or cryopreservative can be added as needed. Aliquot and store at -20C for longterm storage. Dilute immediately prior to use.

Key calcium ion sensor involved in the Ca(2+)-triggered synaptic vesicle-plasma membrane fusion and in the control of neurotransmitter release at these output synapses. Interacts in a calcium-dependent manner to the presynaptic SNARE proteins at ribbon synapses of cochlear inner hair cells (IHCs) to trigger exocytosis of neurotransmitter. Also essential to synaptic exocytosis in immature outer hair cells (OHCs). May also play a role within the recycling of endosomes (By similarity). {UniProtKB:Q9ESF1}.

Immunoblotting: use at 1-5ug/mL. A band of ~220kDa is detected. <br><br>Immunofluorescence: use at 2-10ug/mL. <br><br>These are recommended concentrations. <br><br>Enduser should determine optimal concentrations for their applications.

This product is stable for at least one (1) year at -20°C to -70°C. Reconstituted product should be stored in appropriate aliquots to avoid repeated freeze-thaw cycles.

Otoferlin protein is the product of the OTOF gene. Otoferlin is present in the brain and the cochlea of the inner ear where sound is processed. Hearing relies on Ca2+ influx-driven exocytosis of synaptic vesicles at the ribbon-type active zones of hair cells. The presence of several C2 domains in otoferlin, some of which bind Ca2+, suggest that otoferlin is a Ca2+ sensor for fusion in inner hair cell (IHC) synapses.
